CLP Standards for ICP & ICP-MS Our Contract Laboratory Program (CLP) standards allow you to Calibrate with Confidence®. The standards are to be used in conjunction with the Statement of Work for Inorganic Analysis; Multi-Media/Multi-Concentration Document Number ILM 05.3/ISM 01.2.
The final ICP check, performed in our own laboratories, is your stamp of assurance. We calibrate our instruments with traceable reference materials and show you the actual found value of the solution you receive, not just an ideal, calculated number as so many other standards manufacturers do. The combination of elements, concentrations and matrices listed have been diagnosed by SPEX CertiPrep for convenience of use and stability.
US EPA SOW ILM 05.3/ISM 01.2 gives specific procedures for the methods of analysis, target elements, and concentrationlevels. Standards are specified not only by the elements present and their relative concentrations, but also the order and frequency of running standards, blanks and samples. Details of these specifications may be found in the US EPA SOW ILM 05.3/ISM 01.2 in the following sections:
• Exhibit C, Inorganic Target Analyte List (TAL)
• Exhibit D, Analytical Methods
• Exhibit E, QA/QC Requirements
Instrument Calibration for CLP Methods
May be used separately or mixed together for preparation of the analytical curve. When mixed, these solutions will yield a standard containing all of the elements in the Target Analyte List (TAL). Instruments must be calibrated daily, every 24 hours, or each time the instrument is set-up. Calibration standards must be prepared fresh for each analysis and discarded after use. A dilution of 10-fold is suggested. Antimony and mercury can be diluted as required.
For ISM 01.2, at least one of your calibration standards must be at the Contract Required Quantification Limit (CRQL). See ISM 01.2 sections for CRQL standards
